One thing...
When someone says your 'front end sees the collision, you collide', that does NOT mean if you look away from the collision in the game you won't ram. Your view keys won't protect you, its your computer telling the server what position you are in, not the view keys.
I actually had a player tell me that one once.
Hilarious!
I once had a guy whine that he collided and he LOOKED away so his FE didn't "SEE" it.
He would fly right at 'em and just before the moment of impact he would look back.
(sigh)
Also what is being said about the film viewer is correct. The film viewer isn't 100% accurate. It is only off by mere feet but when flying through a hanger 1-3' can make a diff.
Stiglr, in the example you gave it still boils down to if your planes touched or not on your FE.
A player warping, or a buff drone warp, is totally diff. subject matter than what is being discussed.
But...
Even in your examples, if your plane touches the warpy plane or drone on your FE there is a collisions.
If they do not there isn't.
Until we have instantaneous internet where there is no lag what so ever what HTC has Coaded is the best possible solution.
My advice is just don't hit them.
